Sorting shapes and making shapes from shapes

Sorting shapes in a Venn diagram

Building on from our work with triangles we have been thinking about quadrilaterals. Did you know that a quadrilateral is 'a polygon with four sides and four vertices or corners'. We had to think carefully about triangles and quadrilaterals when we were sorting their different properties. We are all able to remember the isosceles triangle, two equal sides and two equal angles, really well now after one of us called it an isausageles! We all laughed at that and it has helped us to remember it. It just sounds so tasty.

Combining triangles

We have also been using equilateral triangles, three equal sides with three equal angles of 60 degrees, to make a range of different shapes. It was quite a challenge and as Dr. Suess says, "We puzzled and puzzled until our puzzler was sore." Working with a partner helped us to solve the tricky problems we were given.

This one really got us thinking!

Investigating Triangles

Which type of triangles can you see here?

In maths we need to cover a wide range of subject areas and this week we have started to work on geometry. Just in case you didn't know, geometry is, 'the area of maths dealing with solids, surfaces, points, lines, curves and angles, and their relationships in space'.
In class we have been using practical resources to help us think about the different types of triangles and which particular things make them different. We used a great deal of mathematical language when talking about right-angled triangles, equilateral triangles as well as scalene triangles. 

Geo boards work well for making triangles.

What can you say about the properties of these triangles?

Counting in multiples of 10.

Continued good autumn weather has given us more opportunities to get outside for maths. Just the other day some of us were outside working on sequencing multiples of ten. We worked with a partner to develop number walls with sequences increasing by 40, 50, 60, 70, and 80. It gave our friends playing football at lunchtime something  to think about too!

From the start ...

...to the finish we had to think carefully.

Almost at a four digit number.

Working together helps us learn and is fun.

Thinking about our learning.

As we progress through the different areas of maths we are bringing a positive approach to our learning along with taking the time to stop and think. After working on four digit numbers we all took a moment to note down what we have learnt about numbers involving thousands.
